v Application iiled' October 13, 19,25. Serial No. 62,282. Y

T all whom t may concern.' y

Be it known 'that we, CriuLL BRiGNoLo, THONY. Amann and Ginsnrrn BnieNono,

citizens of the United States, residing atl This invention relates to` improvements p in bumpers, the general object being to provide a resilient supporting means for the .bumper uponthe hanger bracket upon the :motor vehicle chassis kwhereby a resilientuniversal support may be had for the bumper which ,will give in vany direction when .striking an object and yet bei-ng limited as. to its resilient forces andi give the' desired effect as a bumper )and yet absorb the usual shock experienced rin.striking any obj ect. f

Another object of our invention resides in.

the construction of parts and the arrangements thereof in the support of thebumper whereby the resilient supporting meansmay be rigidly secured to the bumper and tothe hanger Y support upon t ie motor vehicle chassis to-which the present invention is applied. i i

YVith theaboveaand other-objects in view, the invention further yincludes the following novel features and details of construction, to behereinafter more -fully described, il-

lustratedin the accompanying*drawings and pointed outin theappended claims.

In the drawings :-A Figure 1 :is ay front r bumper.

Figure 2 the associated eludedl thereon.

Figure 3 isa perspective Vof one of the hanger brackets. i

Figure 4; is a fragmentary side elevation of one of the hanger bracketsl illustrating the manner in which. `the resilient supporting means is connected'thereto and with the bumper. f

Figure 5 is a perspective of the elements forming our invention..

Referring to the drawings in detail,

and supporting ymeans' `,in-i

wherein like characters of reference denote corresponding parts, the reference character lO'indi'cates a pair of spaced parallel` bars, auxiliary strips 11 formed integral upon the inner meeting` edges thereof in forming an elevation of our isaftop yplan view ythereof' ornamental design 12 therebetween and centrally ofA the length of the bumper-.Kas cornpleted. The oppositeend portionspffthe bars forming the bumperV are positioned upon theinner side of plates 13 having inwardly extending apertured ears 14 provided upon therespective ends thereof thus:

i forming the enclosure'forthe reception of the bai-s1() forming 'thebumper and imme-A diately behind the respective endvofa spring plate 15 ysecured as at k16 intermediate the length` ofthe plate 13. The forward end convolutions 17 of coiled vspringsvrr18 encircles portions of bolts 19 extending through the respective; end'of theplates L13 andf correspondingend off the spring plate 15 'andY the-apertured earsy 14' insecuring the forwardconvolutions 17 of thesprings 18 rigidly thereto in lthe .support of. the buni'per- 'asv completed, kupon Athe forward endsY of the springs 18.

In order to provide means for. supporting` the, oppositeends of the springs V18l upon.v i

a motorvehicle chassis, not. shown, we pro-4 vide hanger brackets 20 supporting. plates 21 upon the forward side which in turnv 1n#- cludes vertically disposed channelY portions 21- upon theirv inner sides: against the 'forward sidefof the plates21^for therecepe tion of the intermediatepontionsof'gUfbolts 23 therein, also iincludingan offset springplate 24 Ithereonimmediately' behindffthe plate 25 terminating .in inwardly .extending apertured earsV 26. r The.,adjacent end-'spring convolutions /27 ofthe' springs 18 are positioned immediately behind the 'ears'26and while cups `28r also4 included 'upon the U'- encircle the. yforward* ends of the Ufbolts Y23- bolts23 between the. springplatesl24. and i i plates forwardly `thereof and form; anV enclosure andv ornamental vdesign for the convolutions 27 ofthe springs 18.

It-is thus to benoted from the. foregoing 25 have. their {side walls extendingfonce, thus eliminating the usual shock when encountering an object or colliding with another motor vehicle.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described our invention what is claimed is l. A bumper for use upon motor vehicles comprising anchoring brackets arranged at appropriate points thereon, U-bolts supported upon the forward portion of the anchoring brackets, plates secured to the bumper at appropriate points in the length thereof, and springs having their respective end convolutions secured to the U-bolts and plates providing a combined universal joint and shock absorber for the bumper.

2. A bumper for use upon motor vehicles comprising anchoring brackets arranged at appropriate points upon the motor vehicle chassis, grooved plates secured to the forward portion of the anchoring brackets journaling the intermediate portion of the U-bolts thereuponyplates arranged at spaced intervals the length of the bumper and terminating in oppositely inwardly extending apertured ears for the reception of fastening elements therein, and springs having their respective end convolutions encircling the fastening means and U-bolts providing a combined universal joint and shock absorber for the bumper.

3. A bumper for use upon motor vehicles comprising anchoring brackets arranged upon the motor vehicle chassis, grooved plates arranged upon the forward portion of the anchoring brackets, U-bolts having their intermediate` portions arranged within the channels of the plates and having their respective ends extending forwardly thereof, a plate having inwardly extending` apertured ears upon the respective ends thereof receiving the corresponding ends of the U- bolts therein, plates arranged at spaced intervals in the length of the bumper and terminating at their ends in oppositely inwardly extending apertured ears, fastening means positioned within the apertured ears of the plates, and springs having their respective end convolutions encircling the fastening means and respective ends of the U- bolts providinga combined universal joint and shock absorber for the bumper.

4. A bumper for use upon motor vehicles comprising anchoring brackets arranged upon the motor vehicle chassis, grooved plates arranged upon the forward sides of the anchoring brackets, U-bolts having their intermediate portions positioned within the grooved portions of the grooved plates, and intermediately offset spring plates being positioned upon the U-bolts, a plate terminating in oppositely disposed apertured ears being received upon the U-bolts, plates arranged at spaced intervals in the length of the bumper and terminating in oppositely inwardly extending apertured ears for the reception of fastening elements therethrough, and springs having their opposite end convolutions encircling the fastening means and U-bolts beneath the apertured ears of the corresponding plates providing a combined universal joint and shock absorber for the bumper.

5. .A bumper for use upon motor vehicles comprising anchoring brackets arranged upon the motor vehicle chassis, grooved plates being positioned upon the for Yard portions of the anchoring brackets, iJ-bolts having their intermediate portions positioned within the grooved portions of the plates and having their respective ends extending forwardly thereof, intermediately offset plates having their respective ends received upon the corresponding ends of the tri-bolts, cup-shaped members arranged upon the forwardly extending ends of the tl-bolts, plates terminating in inwardly and oppositely disposed apertured ears and received upon the forwardly extending ends of the U-bolts, plates arranged at spaced intervals in the length of the bumper and terminating at their ends in oppositely inwardly extending apertured ears, offset spring plates beingV arranged upon the inner sides of the plates and extending immediately behind the oppositely inwardly disposed apertured ears and receiving fastening elements therethrough from the plates and bumper, and springs having their respective end convolutions encircling the fastening means and U-bolts beneath the inwardly disposed apertured ears providing a combined universal joint and shock absorber for the bumper.

ln testimony whereof we aflix our natures.
